Introduction And Importance: Melanoma is a malignant skin neoplasm with a high metastatic potential. Several reports have shown that metastatic melanoma has a predilection to metastasize to the GI tract; however, diagnosing metastatic melanoma as a cause of intussusception has been reported in only few cases with variable presentations.
Case Presentation: We present the case of a 48-year-old woman with a long history of metastatic melanoma who presented with recurrent enteric intussusception due to a melanoma lesion acting as a pathologic lead point despite immunotherapy treatment. We contribute the management plan, diagnostic modalities, and surgical approach of this rare form of adult intussusception in guidance of future management plans.
Clinical Discussion: The variability in presentation of adult intussusception makes diagnosis difficult and the lack of consensus on management and surgical strategies poses challenging hurdles. A diagnostic laparoscopy followed by reduction and resection of the intussuscepted lesion in a small surgical field is an effective and beneficial palliative procedure with favorable outcomes. Our patient developed intussusception despite receiving a trial of dual immunotherapy after chemotherapy.
Conclusion: It may be insufficient to control disease even with dual immunotherapy after chemotherapy. Further studies are needed to determine the optimal surgical and oncological management in treating gastrointestinal metastasis of malignant melanoma.

Background: In malignant melanoma, liver metastases significantly reduce survival, even despite highly effective new therapies. Given the increase in metabolic liver diseases such as metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH), this study investigated the impact of liver sinusoidal endothelial cell (LSEC)-specific alterations in MASLD/MASH on hepatic melanoma metastasis.
Methods: Mice were fed a choline-deficient L-amino acid-defined (CDAA) diet for ten weeks to induce MASH-associated liver fibrosis, or a CDAA diet or a high fat diet (HFD) for shorter periods of time to induce early steatosis-associated alterations.

Background: While prosthesis-associated malignancies have been acknowledged, awareness among surgeons and patients in the ophthalmologic field remains limited, despite the frequent occurrence of prosthesis-related surgeries. We aim to address this gap through a scoping review of malignancies following ophthalmologic surgeries involving various foreign device/prosthesis/implants.
Methods: Following PRISMA guidelines, we conducted a review using PubMed and Embase for studies on cancer and ophthalmic prostheses/implants.

Aim: Merkel Cell Carcinoma (MCC) is a rare skin cancer with a rising incidence worldwide. Anti-programmed death-1/ligand-1 (anti-PD-(L)1) therapies are effective for the treatment of advanced MCC. This study examines patterns of response / progression of advanced MCC to anti-PD-(L)1 therapies and describes subsequent management.

Introduction: Advances in modern therapies have improved outcomes for patients with melanoma brain metastases (MBM), though prognosis remains poor. The optimal treatment strategy for patients who do not meet clinical trial inclusion criteria is unclear.
Methods: This study included all patients with MBM diagnosed in Denmark between 2015 and 2022, identified through the Danish Metastatic Melanoma Database (DAMMED) and local surgical and radiotherapy records.
